The vicinal "G'H, "N-'H and %-"N spin coupling constants were obtained from the 'H and =C NMR spectra of various ionic forms of the amino acids phenylalanine, a-aminobutyric acid and p-alanine, and also from their "N isotopomers. It is concluded that the "C-'H and =N-lH coupling constants are reliab
## Abstract The first successful observation of the vicinal ^15^N,^13^C spinโcoupling constants in a series of amino acids, comprising Val, Ile, Leu and Thr, in which the ฮฑโnitrogens are fully replaced with ^15^N, is described. A Karplusโtype dihedralโangle dependence was noted for the coupling con
